The U.S. has added dozens of Marines to the security details at embassies in Jordan, Israel and Turkey. Five US defense officials tell NBC News the move comes in light of concerns about unrest linked to the opening of the U.S. embassy in Jerusalem. The officials say the State Department and the Pentagon are also considering more U.S. military security at embassies in a half dozen other countries in the Middle East with histories of large-scale demonstrations, like Lebanon, Egypt and Pakistan.
